Investigation of the Association between Surgeon Sex and Laparoscopic Device Ergonomic Strain in Gynecologic Surgery

Abstract

To assess whether female compared with male sex is associated with greater ergonomic strain with the use of 4 advanced energy laparoscopic devices (LigaSure, HALO PKS, ENSEAL, and Harmonic scalpel). Online survey distributed by e-mail using the REDCap platform (Vanderbilt University). All responses were anonymous. Nationwide survey in the United States. Gynecologic surgeons were surveyed through the Society of Gynecologic Surgeons listserv and 4 obstetrics and gynecology departmental listservs. The survey was distributed between May 1, 2020, and November 1, 2020. The primary outcome was the presence of physical complaints owing to laparoscopic devices. Descriptive statistics compared surgeon characteristics and ergonomic symptoms. Logistic regression was performed, adjusted for surgeon characteristics. The response rate was 39%, comprising 149 women (78%) and 41 men (22%). Women compared with men had a significantly younger age (mean, 34 vs 44 years; p <.01), had smaller glove size (mean, 6.5 vs 7.5; p <.01), had shorter height (median, 66 vs 71 inches; p <.01), and were less frequently in practice for >10 years (19% vs 49%; p <.01). Women significantly more often reported physical complaints related to the use of laparoscopic devices (79% vs 41%; p <.01). Women reported that all devices had too large a fit for appropriate use (p <.01). Women were found to have 5.37 times the odds of physical complaints attributed to the use of laparoscopic instruments (crude oods ratio, 5.37; 95% confidence interval, 2.56-11.25); with adjustment for glove size, age, and laparoscopic case volume and duration, this was no longer significant (adjusted odds ratio, 2.02; 95% confidence interval, 0.59-6.93). Women significantly more often report physical complaints and inappropriate fit of the LigaSure, HALO PKS, ENSEAL, and Harmonic scalpel. Female sex is associated with 5-fold greater odds of physical complaints with laparoscopic device use. Further investigation of the surgeon factors underlying device-related strain is a critical next step to understanding and reducing surgeon ergonomic injury.
